Re: Cleaning and white spots
1) just kind of wave the vacuum over teh plants if they get stuff on them, you really don't need to vacuum close to teh plants.
2)Plant,Plant Plant!! Plants are one of teh best things you can do for your tanks and fish.
3)Cory love to have others of their kind. Is the loner a different kind of cory than the others?
4)Most otos don't move alot but should move some. they too like others of their kind. are the other fish bothering him?
5)How to keep your guppies from breeding? keep the sexes seperate. Then after the females have babies seperate the sexes. Female guppies can have up to four batches of fry from one mating. You could always put teh females in with larger fish and let the larger fish eat the fry.
6) the white spots are probably planaria(tiny white worms). they are harmless and most fish will eat them. they are usually a sign your feeding too much/ infrequent water changes. So cutting down on feedings and doing at least 25- 50% water changes each week should do it.
sorry about your Oto, we have all done things by accident that we regret.
